自己搭建git 代码服务器

2022-06-10 07:57:28

使用git服务器的工程师都需要生成一个ssh的公钥

~/.ssh$ ssh-keygen

Generating public/private rsa key pair.

……………………

然后一律按回车，完成后会在home目录下的.ssh目录中生成两个文件id_rsa(私有密钥)和id_rsa.pub(公钥)。

将生成的公钥id_rsa.pub发给git仓库的管理者。

然后在服务器端：

sudo adduser git

su git

cd ~

mkdir .ssh

在git用户新建一个.ssh的目录，将开发者的SSH公钥添加到git这个用户的authorized_keys这个文件当中。如有zhangsan,lisi两个开发者。

cat /tmp/id_rsa_zhangsan.pub >> ~/.ssh/authorized_keys

cat /tmp/id_rsa_lisi.pub >> ~/.ssh/authorized_keys

建立一个空的仓库

cd work

mkdir project.git

cd project.git

git --bare init

使用--bare会初始化一个不带任何工作目录的仓库，不会看到工程源码。

开发者端：

若没有仓库的情况下，需要首先新建一个仓库。在需要建立仓库的，目录下执行以下的命令。

cd my_project

git init

git add . (将所有代码加入工程管理)

git commit -m "xxx project initial commit"

git remote add origin git@localhost:/home/git/work/project.git (即：用户名@网络地址:/home/git/work/project.git)

然后执行：git push origin master

如果出现以下错误：

The authenticity of host 'localhost (::1)' can't be established.
RSA key fingerprint is eb:e3:e2:36:84:64:23:f2:b8:7b:a0:4c:ef:d4:9e:7d.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.

执行一下：$ssh localhost -o StrictHostKeyChecking=no

(用ssh登录一下就好使，就不会弹出The authenticity of host 'localhost (::1)' can't be established.的错误了。)

然后再退出ssh登录。

然后：

a@ubuntu:~/linux-2.6$ git push origin master
Counting objects: 56913, done.
Compressing objects: 100% (56081/56081), done.
Writing objects: 100% (56913/56913), 150.96 MiB | 4.08 MiB/s, done.
Total 56913 (delta 4433), reused 0 (delta 0)
To git@localhost:/home/git/work/project.git
* [new branch] master -> master
a@ubuntu:~/linux-2.6$ ls

就好了。

小组内开发者b下载代码时：

b@ubuntu:~$ git clone git@localhost:/home/git/work/project.git
Initialized empty Git repository in /home/b/project/.git/
The authenticity of host 'localhost (::1)' can't be established.
RSA key fingerprint is eb:e3:e2:36:84:64:23:f2:b8:7b:a0:4c:ef:d4:9e:7d.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: The remote end hung up unexpectedly
b@ubuntu:~$

同样执行一下：
b@ubuntu:~$ ssh localhost -o StrictHostKeyChecking=no

然后：

b@ubuntu:~$ git clone git@localhost:/home/git/work/project.git
Initialized empty Git repository in /home/b/project/.git/
git@localhost's password:

分析 ssh localhost -o StrictHostKeyChecking=no可能不会检查公钥的正确性就让登录了。
